TRANSCRIPT
Segway RoboticsAn Introduction using Control Theory
• Segway robot is a complicated robotic system. It is a type of robot which balance on two wheel.
• The first Segway robotics based model was introduced in market by DEAN KAMEN with DOUG FIELD.
• Name of product: Segway PT.
• A user commands the Segway to go forward by shifting their weight forward on the platform, and backward by shifting their weight backward.
• Uses Gyroscopic sensors and fluid-based levelling sensors detect the weight shift.
Bla Bla Bla ………..
Concept behind Segway Robotics
• Segway Robotics is based on classical control theory.
• Works on discrete time system.
• The model of Segway Robot is a combination of both UNICYCLE MODEL and INVERTED PENDULUM MODEL.
Linear System
• But all the models are not linear.
• Rather most of them are non-linear in nature
Linearization
Inverted Pendulum
Unicycle
Stability
Re(l)<0
Re(l)=0
Re(l)≤0
State Feedback
Stabilization using Pole Placement
Controllability
• Then the system is Completely Controllable
• Pole placement is then possible
Segway Robot Again !

Therefore, System is not completely Controllable!
But here we can consider only v and w of the uniclycle part
4Now,
Therefore, System is completely Controllable!
